Objectives: To evaluate the effectiveness and safety of the single step dilatation of the pelvicalyceal system using the Webb target dilator.
Methods: Thirty consecutive patients who underwent PCNL using the Webb dilator were compared with 30 patients in whom sequential dilatation was done. The two groups were similar as regards age, stone location and degree of hydronephrosis.
Results: The Webb dilator was associated with a lesser time for tract dilatation as compared to the sequential dilatation group. There were no significant complication in either group. There was a higher incidence of failure of adequate access to pelvicalyceal system with the Webb dilator group if the pelvicalyceal system was not dilated.
Conclusions: The Webb target dilator is a safe, rapid and effective method of tract dilatation during PCNL and is associated with significantly shorter time in tract dilatation as compared to the sequential dilatation group. However it is not suitable for non-dilated pelvicalyceal systems. |
